| Type: | Domain | Name: | Pectinesterase inhibitor domain |
| Description: | This domain inhibits pectin methylesterases (PMEs) and invertases through formation of a non-covalent 1:1 complex []. It has been implicated in the regulation of fruit development, carbohydrate metabolism and cell wall extension []. It may also be involved in inhibiting microbial pathogen PMEs. It has been observed that it is often expressed as a large inactive preprotein []. It is also found at the N-termini of PMEs, suggesting that both PMEs and their inhibitor are expressed as a single polyprotein and subsequently processed. It has two disulphide bridges and is mainly alpha-helical []. | Short Name: | Pectinesterase_inhib_dom |
